powerpc: Add self-tests of the feature fixup code

This commit adds tests of the feature fixup code, they are run during boot if CONFIG_FTR_FIXUP_SELFTEST=y. Some of the tests manually invoke the patching routines to check their behaviour, and others use the macros and so are patched during the normal patching done during boot. Because we have two sets of macros with different names, we use a macro to generate the test of the macros, very niiiice.
